Tetragonia

New Zealand Spinach, T. tetragonioides, is a half-hardy, short-lived perennial that makes a good substitute for Spinach, during the hot days of summer. These plants have interesting triangle-shaped leaves that are dark green on top and glistening underneath. Their short runners grow about 2 to 3 feet long in the North, but will grow longer and can be trained up trellises in warm climates.

Pot Cultivation

This vegetable grows better in sandy or sandy loam soil. They should be planted 12 inches apart, in rows 3 feet apart. They are resistant to heat and dry soil, but will do much better if watered occasionally. In very hot climates, some afternoon shade will prevent them from wilting. This plant is very handsome in a pot. Gather only 2 or 3 tender tip leaves; older ones tend to have a very strong taste. The very small, succulent leaves can be chopped and added to mixed green salads. Don't use too much, however, because they can be very overpowering due to the high calcium oxylate content.

Propagation

Soak seeds in warm water over night. Plant them inside in peat pots filled with sandy soil at a 70- to 80-degree temperature. Transplant when the weather is safe. They may also be planted straight outside when the weather is warm and settled. The seeds may germinate slowly and irregularly, but once they are established, they will drop seeds and start new plants.
